Patent number: 10526014Abstract: A regulable vibration damper, which may be utilized in a vehicle chassis, for example, may comprise a cylinder barrel that contains hydraulic fluid in sealed-off fashion, a piston that is axially movable within the cylinder barrel along a cylinder barrel axis and that divides the cylinder barrel into two working chambers, and a piston rod oriented parallel to the cylinder barrel axis and that is connected to the piston. The piston may comprise at least two fluid leadthroughs that connect the working chambers. A first valve assembly for damping piston movement in a first actuation direction may be arranged at a first fluid leadthrough, and a second valve assembly for damping piston movement in a second actuation direction may be arranged at a second fluid leadthrough. In the piston, one or more bypass ducts with throughflow cross sections of different size for the two throughflow directions may form fluidic connections between the two working chambers that bypass the vestibules.Type: GrantFiled: October 22, 2015Date of Patent: January 7, 2020Assignees: THYSSENKRUPP BILSTEIN GMBH, THYSSENKRUPP AGInventors: Wolfgang Hamers, Dmitrij Smeljanskij

Patent number: 10526015Abstract: A push arm is coupled to a vehicle frame proximate an intersection of a first side member and a first cross-member. A rear surface of the push arm is located adjacent to a front suspension structure with a gap defined therebetween. The push arm extends forward and laterally outward such that a front surface of the push arm is located outboard of and spaced apart from a front end of the first side member. An energy absorbing structure is positioned within the gap and is attached to the rear surface of the push arm and is spaced apart from the front suspension structure in a non-impacted state. The energy absorbing structure is configured such that in response to an off-center impact event, impact force to the energy absorbing structure pushes the energy absorbing structure into contact with the front suspension structure.Type: GrantFiled: March 13, 2018Date of Patent: January 7, 2020Assignee: Nissan North America, Inc.Inventors: Takemi Nishikawa, Kazunori Iimi, Takao Tani, Hideo Aimoto, Naoki Kamizawa, Patrick Dean Grattan, Perry McConnell

Patent number: 10526017Abstract: A structural member extends in a vehicle longitudinal direction. An off-center impact structure has a first member and a second member. The first member has a linear portion and an offset portion both having a hollow interior. The first linear portion extends through a first opening in the structural member in a direction perpendicular to the structural member and further extends in an outboard direction from the structural member. The offset portion is angularly offset from the first linear portion and extends laterally outboard and forward relative to the structural member. The second member has a first section and a second section. The first section is disposed within the hollow interior of the linear portion of the first member and the second section extends through of an opening in the first member outboard from the opening of the first member away from the hollow interior.Type: GrantFiled: April 30, 2018Date of Patent: January 7, 2020Assignee: Nissan North America, Inc.Inventor: Patrick Ramses Grattan

Patent number: 10526018Abstract: A front end module (10) has a cross member (12) that connects to longitudinal members (14) of a motor vehicle frame for carrying away loads from a bumper. An actuating rod (18) can pivot relative to the front wheel (22) due to relative movement of a part of the cross member (12) in the direction of travel of the motor vehicle during a small overlap crash. The actuating rod (18) in the pivoted-out state for rotating the front wheel (24) radially within a wheel rim ring (28) of the rim (22) can be gripped at the rim (22). Damage to the front wheel (24) by plastic deformation of the front end module (10) and by the actuating rod (18) can be avoided to permit satisfactory crash behavior of a motor vehicle.Type: GrantFiled: November 27, 2017Date of Patent: January 7, 2020Assignee: Dr. Ing. h.c.
